use as a supplement to the cereals, consequently the high 

 value of dairy products, skim milk, buttermilk and whey 

 in the feeding of swine.. 



The same thing applies in chicken feeding and in feed- 

 ing the laying hens. Any of you people or any of your 

 neighbors using a ration made up of corn, wheat, oats and 

 other grains, along with such feeds as linseed meal, wheat 

 middlings, and gluten feed, any of these sereal proteins, 

 cannot expect efficient production from your hens on that 

 ration, on account of the poor quality of the proteins. By 

 the addition of dairy by-products, meat meal or scraps, the 

 efficiency of that ration san be tremendously increased. 



What is the importance of quality proteins in feeding 

 the dairy cow? In feeding the dairy cow or sheep or 

 horses the quality of proteins in the feed is not anywhere 

 near of as much importance as it is in feeding swine or 

 poultry, for this reason and under these conditions only: 

 when these animals are supplied with plenty of legume 

 hay, they already get proteins of high quality. If a man 

 was using timothy hay and oats straw as a roughage al- 

 lowance for his dairy cows, he would need six times as 

 much, nearly, as a man feeding swine would; but if a dairy- 

 man shall use a liberal allowance of legume hay for his 

 dairy cows, he does not need to pay very much attention 

 to the quality of proteins in his ration. In other words in 

 figuring out which supplement to use under those condi- 

 tions he can figure out and find which protein, which sup- 

 plement furnishes digestible food protein the cheapest and 

 largely govern his decision on that basis. If cottonseed 

 furnishes protein cheaper than linseed meal, he can use 

 cottonseed meal. 



If a man is using gluten feed, even as the main source 

 of protein, if he is using legume hay and corn silage, gluten 

 feed is a corn by-product and does not contain the corn 

 volume. Gluten feed furnishes the same kind of protein 

 as corn, having certain deficiencies, but an entirely differ- 

 ent fat when fed under like conditions, and makes a good 

 supplement when used with legume hay and silage. 



That is an exceedingly important point to bear in
